The use of A1STA32 can significantly reduce the wiring time I/O 32 type of connector assembly,
Neither welding, without thread stripping,
It only needs to cut a wire and insert the wire into the terminal hole of the A1STA32,
A1STA32 in the blade will cut wire insulation surface,
To make contact and hold a good conductor A2SCPU PDF. 5 slots.
No need to install power.
For QnA/A series.
Switch volume control is designed to,
According to the current input combination of the switch quantity and the history of the input sequence,
So that PLC generates the corresponding switching output,
In order to make the system work in a certain order A2SCPU PDF A2SCPU
So, sometimes also known as the order control.
And sequential control is divided into manual, semi-automatic or automatic.
And the control principle is decentralized, centralized and hybrid control three.
Each scanning process. Focus on the input signal sampling. Focus on the output signal to refresh A2SCPU PDF.
Input refresh process. When the input port is closed,
Program in the implementation phase, the input end of a new state, the new state can not be read.
Only when the program is scanned, the new state is read.
A scan cycle is divided into the input sample, the program execution, the output refresh MITSUBISHI Programming Manual.
The contents of the component image register are changed with the change of the execution of the program.
The length of the scan cycle is determined by the three.
CPU the speed of executing instructions.
Time of instruction.
Instruction count.
Due to the adoption of centralized sampling MITSUBISHI Programming Manual.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
System program memoryy for storing system program,
Including management procedures, monitoring procedures, as well as the user program to do the compiler to compile the process of interpretation MITSUBISHI Programming Manual A2SCPU Manual .
Read only memory. Manufacturers use, content can not be changed, power does not disappear. DC input points: 8 points.
Input voltage and current: 7mA, DC24V.
Response time: 10ms.
8 point /1 a public side.
Positive / negative sharing.
24 point terminal station.
MITSUBISHI PLC protection and chain procedures.
Protection and chain is an indispensable part of the program, must be carefully considered.
It can avoid the control logic confusion caused by illegal operations.
MITSUBISHI PLC initialization procedure. After MITSUBISHI PLC on power, the general need to do some of the initial operation,
In order to start making necessary preparations, to avoid the wrong operation of the system.
The main contents of the initialization program are: to some data area, counter and so on,
Data needed to restore some of the data area,
Set or reset some relays,
For some initial state display, etc..
MITSUBISHI PLC prograam simulation debugging
The basic idea of program simulation debugging is,
In order to facilitate the form of simulation to generate the actual state of the scene,
Create the necessary environmental conditions for the operation of thee program A2SCPU Manual A2SCPU Programming Manual.
Depending on the way the field signals are generated,
The simulation debugging has two forms of hardware simulation and software simulation.
